UNITED STATES" 1,542,759 PATENT OFF-ICE- WILLIAM E. BAKER, OF ERIE, PENNSYLVANIA, ASSIGNOR TO WEBB ENGINEERING COMPANY, OF ERIE, PENNSYLVANIA, A COMMON-LAW TRUST.

To all whom it may concern: 7

Be it known that I, WILLIAM E. BAKER, a citizen of the United States, residing at Erie, in the county of Erie and State'of Pennsylvania, have invented certain new and useful Improvements in Fluid-Fuel Burners; and I do hereby declare the fol-,

N struction thereof.

The object of my invention is to, provide means whereby the wall of the burner may be protected from excessive heat and thereby-will not become warped and distorted.

These and other features of my invention are hereinafter describedand pointed out, and are illustrated in the accompanying drawings in which v Figure 1 is a central longitudinal section of a fluid fuel burner embodying my lIlVGl'lr 7 tion.

Figure 2 is a fragmentary view of the face side of the burner.

Figure 3 is a side elevation of one of the burner nipples of my apparatus.

In these drawings A indicates a plate preferably of sheet metal, which is provided with a plurality of openings a, spaced as may be desired to properly distribute the burner tips hereinafter described within the bounds of the face of the burner structure. c

The rear, or back-side, of the plate A is enclosed by a box-like mixing chamber A into which air and fluid fuel is supplied by means ofthe air tube B and fuel pipe B, the said air and fuel being deflected toward the plate A by means of a deflector G.

The sideand end plates D and D extend downward beyond the plate A, as shown at d to a point substantially adjacent to the lower ends of the burner nipples E.

The burner nipples E are preferably cylindrieal inshap'e, having formed around one end thereof an annular shoulder 6 adapted to'seat against the under side of the v a g FLUID-FUEL BURNER.

Application filed March 3, 1924. Serial No. 696,542.

inserted into the openings a is then flanged outwardly over the upper side of said plate as shown at 6', so that said nipples are firmly secured in said openings at.

The opposite, or lower ends of the nipples E are enlarged, internally, to form an internal annular shoulder e therein, against wvhich perforated discs F of lava, or other suitable material are seated, and the edge E of the nipples E are then flanged nwardly over said discs, thereby firmly securing the discs in place in the nipples E.

The'plate A is preferably welded, at its edges, tothe sides and ends D and D of the mixing chamber D, so that the joints are thoroughly sealed.

In order to protect the metal parts of the structurevfrom heat, thespace enclosed by the edges (5 and cl of the side and end. walls of the chamber D, and between the nipples E projecting from the plateA, is filled with asbestos, or other suitable material G, so that the plate A, and walls of the nipples E will not be subjected to the deleterious effects of the fire from the nipples E.

From experience I have found that a burner constructed as herein shown and described will not warp or crack by reason of excessive heat and will at all times be in op-i erative condition.

Having thus fully shown and described. my invention so that others can utilize the same, I do not desire to be limited to the exact construction herein described, as many modifications can be made therein without departing from the scope of my invention, therefore what I claim as new and desire to secure by Letters Patent is: I

In an apparatus of the class described, a plate having a plurality of openings therethrough, a series of nipples secured in said openings, walls enclosing said plate and forming an enclosed chamber over one side of said plate and forming a flange-like projection around the face of said plate, a series of nipples secured in the openings in said plate perforated discs of refractory mate rial secured in the opposite end of said nip ples, and refractory heat resisting material filling said flange-like projection around said nipples. i

In testimony whereof I affix my signature.

WILLIAM E. BAKER.
